GCSE - CS - chemistry - structure and bonding

Front

Why do ionic compounds conduct electricity as a liquid and when dissolved but not as a solid?

Back

As a solid, the ions are not free to move and carry charge.

In a liquid/dissolved, the ions are free to move and carry charge

Front

Why do ionic compounds (eg. Sodium oxide) have high melting and boiling points?

Back

Giant structure with strong electrostatic attraction between ions., which require large amounts of energy are needed to break.

Front

What is ionic bonding?

Back

Transfer of electron/s between metals and non-metals.

Electrostatic attraction between oppositely charged ions. They always have a giant structure
